What happens if someone completes a duplicate cpa offer by the same company on a different network? Will the second network accept the completed offer?

I was asking this with an affiliate manager. He said that the system they are using will reject the completion or mark it as invalid. To have the second network accept the duplicate offer completion, I have to use a different e-mail address for each network (if they have the same offer by the same company). Is this true?

I can confirm the first part.

Regarding the new email address: The advertiser could still detect this with cookies and browser fingerprinting. So theoretically (!) you would have to change the IP address, user agent, system details and clear all cookies before. But only theoretically.
